So far this season, the Long Wharf Theatre has presented a somewhat surreal couples comedy (Meteors by Steve Martin); a re-vamp of an Eighties comedy-drama that was surprisingly relevant around election time (Other People’s Money by Jerry Sterner); a strong revival of a great achievement in twentieth-century drama (Samuel Beckett’s Endgame); a brand-new play with a fresh voice about Italian immigrants (Napoli, Brooklyn by Meghan Kennedy), and now, next up, a newish play that takes us back to a moment in the recent past that’s seeming more “historic” every day: Smart People by Lydia R. Diamond is set uring the campaign and election of Barack Obama as the 44th President of the United States in 2008. The play purports to follow up recent Long Wharf successes in presenting abrasive plays that feature people in polite situations having to handle ugly truths.

Ka-Ling Cheung, who plays Ginny Yang in the play, saw the production at Second Stage a year ago in New York, and found it “a sexy play about race” that caused her and the friend she saw it with to talk about it afterwards. It’s a play that “asks important questions” about the puzzle of race relations and the problem of status, and she found she had some questions herself after seeing it. In working on the play with her fellow cast members and director Desdemona Chiang, some of those questions are being answered, and some “will be left to the audience.”

Cheung, who has been working mostly in “classical stuff” since her MFA days at the American Conservatory Theater, welcomes a change to “the fun of contemporary language” with a small cast of four who are all playing characters around the same age. All four characters work in Boston with some connection to Harvard, a setting that one imagines will transfer easily to New Haven and that other big Ivy in our midst. The play focuses on highly educated professionals who, we might imagine, are less tainted with racist ideas than people more regionally based and less educated. But that comfortable assumption is precisely what Diamond’s play wants to question, with humor and with added romance elements.

Ginny is “an Asian-American professor who has worked hard to be tenured.” She is a psychologist who mainly does research and a little teaching. Cheung sees her as somewhat “hard and brittle” because, as a woman of color, she’s had to prove herself where a white man would get the benefit of the doubt. Though this is academia, Ginny’s situation extends to almost any profession where women are denied the same status and compensation that men receive. Ginny adds comedy to the plot—deliberately acting-out a stereotype at one point—and Cheung likes the challenge of comedy, which is “harder” than serious roles. She’s also intrigued by the way the ensemble cast will also “play crew” during the set changes, which, she says, creates a level of participation by all that adds to the closeness of the characters’ interactions.

“All the characters are provocative and have strong opinions about racism,” and the play handles the “hot topic” as an aspect of both the personal and professional aspect of the characters. When she first saw Smart People, Cheung was excited, as a young Asian-American woman, that the play “had a part for me”; now, she’s excited by how timely the play seems and by the fact that it should give audiences, as it did for Cheung and her friend, “a lot to talk about.”

Smart People opens this Wednesday, March 15, in previews, at Long Wharf Theatre; the official opening is next week, Wednesday, March 22, at 7:30 p.m.
